The honeycomb panel structure has the characteristics of light weight, high strength, low cost, sound absorption, and heat insulation. It is widely used in construction, turnover boxes, military industry, high-speed rail, decoration and other fields. The materials used in honeycomb structure design are mainly composites of the same or different materials such as polypropylene (PP) and aluminum (AL). Under normal circumstances, it must be resistant to high and low temperatures and have high bonding strength in order to be used as a stress-bearing part. The hot melt adhesive films developed by our company have different melting points and can meet the hot pressing process requirements of different customers.
